Is there a maximum file size in Lightroom Classic?

[geoffl18657010]

Hi,

Recently I have been editing huge panorama's in Lightroom Classic>Photoshop. The files are in excess of 1.75GB.

When I save them into Lightroom Classic I have to use PSB's (Adobe Photoshop Large Document file) and the thumbnails get corrupted in Lightroom Classsic. If I then reopen them using 'Edit a copy with Lightroom Adjustments' It corrupts the entire file. If I export the PSB as a jpeg, the jpeg gets corrupted.

Any suggestione (aside from using smaller files!)

Thanks,

Geoff

65K Pixels Long Edge or 512 Megapixels overall. 
I am unaware of any disk size restriction and routinely work with files greater than 4 GB.

Hi Rikk,

Thanks for your reply. Do you also save PSB layered files? 

Ever had any issues with large file sizes?

As Rikk said, he works with files > 4GB. The limitation is not file size anyway, it is image size in pixels, and pixels in one dimension.

If your thumbnails or large size originals (or any originals, really) are getting corrupted, this is almost always due to a hard disk malfunction somewhere.

JPG I think also imposes a smaller maximum pixel dimension of its own. Used to be 10,000px if I recall correctly, though that may have eased since. This should not be a matter of corruption though - it would simply refuse to create.

Thanks @dj_paige ,

You wrote: 'due to a hard disk malfunction somewhere'. I'll start with Repair Disc on my Mac. I store my Lightroom Catalogue and files on a separate Hard Disc. Any other suggestions? Thanks in advance

I am not familiar with MAC diagnostic tools, and so I don't know exactly what Repair Disc does. I would say, in general terms, you want a program that runs a full set of diagnostics on your hard disk, in other words a program that does more than just check for bad sectors, as there can be other problems such a the read/write heads; I don't know if Repair Disc does that or not.

I have many .PSB files in my catalog and have never had issue with large files (MB)
